Comprehensive Aluminum Coil Product Portfolio

We manufacture a complete range of aluminum coil products suitable for diverse industrial applications. Our product lines include:

For projects requiring specialized profiles, our Corrugated Aluminum sheets offer exceptional strength-to-weight ratios with thickness options up to 30mm. These sheets feature high flatness and uniform color consistency, making them ideal for industrial and civil buildings, warehouses, and large-span steel structures. The material's excellent weather resistance and recyclability align with sustainable construction practices.

Technical Advantages of Our Aluminum Coils

Project managers specify our aluminum coils for their superior performance characteristics:

• Mechanical Properties: Tensile strength ranging from 70-400 MPa depending on alloy and temper
• Corrosion Resistance: Superior performance in marine and industrial environments
• Formability: Excellent bending and deep drawing capabilities
• Thermal Conductivity: 120-220 W/m·K for heat exchange applications
• Surface Quality: Mill finish, anodized, or coated options available

Our 5000 series alloys (5052, 5083, 5086) demonstrate particular strength in marine applications with saltwater corrosion resistance exceeding 20 years in properly maintained environments. The 6000 series (6061, 6063) provides optimal machinability for complex fabricated components.

Customization Capabilities for Project-Specific Requirements

Understanding that industrial projects often require tailored solutions, we offer extensive customization options:

• Alloy Development: Custom alloy formulations to meet specific mechanical or chemical requirements
• Dimensional Customization: Widths up to 2,600mm and lengths to 16,000mm
• Surface Treatments: PVDF coating, anodizing, or specialty finishes
• Packaging: Protective wrapping, wooden crating, or custom palletization
• Testing Protocols: Additional quality checks per project specifications

For architectural applications, our color-coated aluminum coils maintain vibrant, bright colors through advanced PVDF coating technology that resists UV degradation. The coating adhesion strength exceeds 5B per ASTM D3359 standards, ensuring long-term performance in harsh weather conditions.

Global Supply Chain and Logistics Support

With exports to 30+ countries, we've developed reliable logistics solutions for international clients:

• FOB, CIF, and DDP shipping terms available
• Containerized and breakbulk shipping options
• Documentation support including CO, FORM A, and mill certificates
• Inventory management programs for JIT delivery
• Strategic stock in key global markets

Our export team handles all customs clearance procedures and documentation requirements, ensuring smooth delivery to your project site. For bulk orders, we coordinate directly with shipping lines to secure competitive freight rates and optimal vessel space.
